ST16C554DIQ64TR-F with UART Interface IC is a quad UART (Universal Asynchronous Receiver-Transmitter) with a 16-byte FIFO memory (first in first out) manufactured by MaxLinear. This integrated circuit is part of the MxLWare family of UARTs and provides four full-duplex universal asynchronous serial communication ports with integrated FIFO memory. It is also powered by a single 3.3V power supply and provides an interface between parallel and serial data formats. It features a four-channel UART controller, 16-byte FIFO memories, ABAUD and TRLED pins, and programmable baud rate generator. This IC also includes more functions such as auto-flow control, on-chip modem control, and I2C/SPI host interface. Additionally, it is suitable for a wide range of applications such as Bluetooth, GSM, and GPS receiver systems.
